15 Claims. 1

This invention relates generally to buildings and more particularly to factory fabricated roof structure therefor.

In the past, buildings of various kinds have been proposed in which the structural members therefor are factory preformed, ready to assemble in order to decreasethe time and consequently the cost of building erection. In some instances, emphasis has been placed on the reduction in the time and cost of erection of such buildings to the detriment of goOd sound construction, particularly with respect to roofs with the result that many of such buildings were not leakproof. In other instances where particular attention was given to assure leakproof roofs, it has usually resulted in sacrificing low fabrication costs, or in rendering erection diflicult and expensive, or both.

Accordingly, it is an object of. the present invention to provide a new and improvedlow cost, readily erected roof and yet one which is leakproof.

Another object of the present invention resides in the new and improved arrangement between roof structural members to insure a leakproof roof.

Another object of the invention is to provide a new and improved panel connecting and ridge construction for insuring a leakproof roof.

A further object of the invention is to provide new and improved roof panels which may be readily secured in place and co-operate with other roof structure to insure a leakproof roof.

Other objects of the invention will become apparent from the following detailed description taken in connection with the seven sheets of drawings in which:

Figure 1 is a fragmentary perspective view of a building having a roof embodying features of the present invention;

Figure 2' is a fragmentary plan view of the building roof;

Figure 3 is a fragmentary isometric view, partly in section, of the roof at one side edge thereof;

Figure 4 is a fragmentary isometric view of a central portion of the roof shown partly in section;

Figure 5 is-a fragmentary isometric view showing one corner of the roof;

Figure 6 is a fragmentary isometric view broken away and partly in section of the roof at one end of the building;

Figure 7 is a fragmentary cross-sectional view of the roof, taken along the line 1'l of Figure 2;

Figure 8 is a fragmentary cross-sectional view of the roof, taken along the line 88 of Figure 2;

Figure 9 is a View in sectionof the roof, taken along the line 9-9 of Figure 2; V

Figure 10 is a view in cross-section of the roof, taken along the line |0lll of Figure 2;

Figure 11 is an isometric view of one of the roof panels, shown removed from the roof, and

Figure 12 is an isometric view of. a panel connector member, shown removed from the roof.

In the drawings, which illustrate a preferred form of the invention, a building, shown in part in Figure 1, includes side walls [0, end walls II and my roof, designated generally by the numeral ii. .The building walls lOand ll may be of any suitable construction and may be supported on any suitable supporting structure or foundation. The roof l2 comprises, in general, a ridge member [3, a plurality of roof panels M, a longitudinally extending panelconnector member or ridge cap l5 and a plurality of laterally extending panel connector members l6. 7 3

The ridge member I3 is supported adjacent its opposite ends on the building end walls I l and in turn supports the inner or upper ends of the roof panels [4 which extend downwardly to and overhang the opposite side walls in on which they are also supported. Preferably, the roof panels M are rectangular and preferably they extend lengthwise between the ridge member and the side walls with side edges of adjacent panels in spaced opposed relation. The ridge cap l5, extending longitudinally of the roof, fits over or caps the ridge member I3-.. On opposite sides of the ridge member, the ridge cap 15 seats on the panels l4 near the upper end edge portions-thereof, along the entire length of the roof to effect leakproof construction. As shown, the laterally extending panel connector members I6 extend from the ridge cap 15 to which they are connected to the outer side edges of the roof panels 14, overlying respectively the spaces between side edges of the adjacent panels, connecting the panels together in a fluid-tight manner.

In the present construction, opposite ends of the ridge member 13 project externally of the building beyond the endwalls ther eof,seating on brackets l! which may be bolted or otherwise secured to the building end walls H. Each of the brackets ll includes a horizontal support or leg Is on which the ridge member seats. Integral with the leg l8 are upstanding opposite side walls [9 andan upstanding end abutment 20 forming a retaining socket for the projecting end portions of the ridge member I3. These side walls I 9 and the abutment '20 restrain side and end movements respectively of the ridge member l3 and 3 these side walls l9 and the abutment 20 in part form a casing for the projecting end portions of the ridge member. The side walls 19 of the brackets preferably extend upwardly and inwardly of the inner edges of the panels I4 to provide weather-tight construction.

The ridge member ['3 comprises a pair of laterally spaced, elongated frame members 2| of C- shape cross section which are spaced apart and connected together by spacer members 22, located at intervals along the length of the frame members. These frame members 2| and; the spacer members 22 are preferably of steel construction for strength and durabilitjp; and; may be welded or may be otherwise suitably secured" together at the factory to provide a rigid unitary structure which may be readily swimginto place; at the erection site. Each of the frame membersZi is provided with outturned upper and lower side reinforcing flanges 23 and 24 respectively, the upper flanges- 23 prefer-ably having outer portions turned down, as at 25; and the lower flanges 24 preferably havingf outer portions turned up, as at 26. r

The roof panel's IW each may be constructed of a pair of thin wooden panels- 2-? secured to opposite sides of a wooden frame 2 8 which preferably includes'a drip" moulding strip 29*- forming the outer or lower-edge ofthe panel. The wooden panels 21' and, its f-ramew may be nailed, cemerited, or be otherwise suitably securedtogether. In order; to insp re a leak-proof panel and further to insure fluid tight joints between the panels, connector members and associatedstructure, each of the panel's M has its upper surface covered.- by a metalli'e cover-sheet 30, preferably steel-,havi-ng anupturned guard'flangee t along the inner or upper edge of -the-p'aneland upturned guard flanges 32 at the sideedges of the panel exceptfor the outer: side} edges ofthe end panels. These upturned'i side and end edge guard flanges are preferablyweldedtogether-at the corners. By formingthese;upturned fianges 3i and 32 out; of, the metallic cover sheet 38' instead of providing flanges separate therefrom; noexposed edges are made available underwhich water might seep. At-the outer side edges of the end roofpanels, the metallia cover: sheet 3!) is bent down and under' thepanel edge to; seal the interior ofthe panelfand further-t effecta flnished' side edge. Also, except; for;theseouter side edges of the endpa'nels; the side edge of each panel is provided with a facing; and reinforcing strip 33: These facin'gandreinforcing strips 33 are preferably sheet steel angle strips-having one leg seating flat against agside edge of'a panel where it may besecured thereto by'screws or by other suitable, means: The sideedge facing strips 33 extend; upwardly above-'theupper surfaces of the panel: M in engagement-- with the outer surfaces of adjacent upturned flanges 32 which thus seal the joints between the facing strips and the panel= edges; covered'thereby. In mass production of the panelsalfl; it'maybe deg sired to form thecove'rsheet 30, withthegfacing strips 33 as integral parts thereof or joined to the upturned flanges; 32: The facing strips- 33'; projectingabove the upper surfaces of the panels in engagement with the outer-surfaces of the sealing flanges 32 also serve toreinforce-these flanges against being 'bentroutwardly; 'Io seal further thelnt'eriorof the panel l4 against entrance of moisture,-the metallicsheet covering 30 is bent down over the outer or-lower-edge of each panel, asat' 34; and wrapped around-and '4 under the dri moulding strip 29 as clearly shown, for example, in Figure 3.

Carried by each of the roof panels It, at the upper or inner edge thereof, is a hanger member 35 for readily attaching the panel to the ridge member 1'3 and for locating the panel in the proper desired position laterally or crosswise of the roof. The hanger member 35 comprises a web portion 36, a; lower, laterally extending flange 3'! and an upper oppositely directed flange 33 having a downturned portion 39. This hanger member 35 preferably extends uninterrupted along the entire width of the panel with the web portion 353' flat against the inner end edge of the panel. The lower flange 3'! of the hanger member 36 seats against the underside of the panel and may be: aperture'd to receive wood screws for securing the hanger to the panel or the parts may be secured together by any other suitable means. Preferably, the hanger web portion 38 and the side edge facing strips 33arewelded together at the corners formed thereby. As shown, the hanger web portion 36 extends-aboV'e-the upper surface of the panel back to'l'iacl z relation with the upturned flange 3| of the panel cover 351*. The hanger web portion 3& reinforces the cover flange 3 I'- and, in addition, ctr-operates therewith to prevent entrance of moisture into the panel along the end edge thereof. The upper" laterally extending flange 38* seats onthe upper' edge portionof the ridge member B with the downturned flangeportion 39 fittingagai nst the inner surface oftheridge frameme'mber. Thus, an upperportion of the web353- the upper flange 39 and the downturned: portion 39 co operate to form a downwardly facing channel or hook to engage the upper portion of one or' theother of the ridge frame members- 2t. addition to the above functions of the hanger member 35, it will be seen that the hangermember also restrains' endwise movement of the panel providing for lo-'- eating and holding the panel in place without need of additionaP'se'curing means,- thus effecting a time saving inerection of the-building.

The panel connector or ridge cap 15 is a hollow elongated member preferably having a top wall 61-, side walls 42 and" a recessedb ottom wall 43 Between the top-and bottom' walls-0f theridge cap 1 5; a suitable woodenfljller'structure M is pref erably provided foradded strength and rigidity. In the present: construction; the ridge' cap IS includes an upper, outer sheetnietal casing'fitting tightly over a lower-sheetmetalcasing to'provide the recessed bottom wall- 63"an'dsupport for the woodfiller: The sidewa1Is--of thetelescoping casings extend downwardly below the recessed bottom wall 43 'an'd' h'ave'outturned flanges 45'; 46 with the outer casing fl'anges- 45 seating on the upper surfaces Of the inner casing flanges as which in turn seat 0n' theupper' surfaces of the roof panels 14. The ridge cap 15 encloses the upper portion of'tlreri'dge-member l 3; upper portions of the hangers-fiend also enclosesthe upturned panelguard-fiang'esi-Hz At'itsopposlte ends, the topwall-M of the ridgecap l 5'may have extendedportions of its top wall 4! bent down, as at l co operating with the'bracket leg! 8' and side walls H! to provide casings enclosing-the projecting end portionscf theridgemember 13. As is more cl-earlyshowrrinFigure12; clearance cutouts 5B are provided in the ridge cap' flanges 45, 45' and extend part way'up the sidesl-2'*of' the ridgecap to cleartheupturnedpan'el flanges 32 and adjacentfacing strips 33 Garried by the ridgecap l 5 to draw and" hold plurality of depending rods 5| in spaced relation along the ridge cap. The rods 5| are T-shaped, in the present instance, having an upper transverse rod portion 52 held in aligned bearings 53 carried by a plate 54 which may be welded to the underside of the member recessed wall 43. Positioned between the spaced, ridge frame members 2 I, the rods 5| extend downwardly through apertures in abutment members or clamps 55 which seat against the lower edges of the frame members 2! Wing nuts 56 may be threaded onto the lower ends of the rods 5| and tightened down against the abutment members 55, thus drawing the ridge cap l5 down toward the ridge member [3. The abutment members 55 are preferably inverted, U-shaped metallic strips having opposite sides 5! fitting snugly between the opposed surfaces of the ridge frame members 2|, thus additionally strengthening the ridge member. At their lower ends, the abutment member sides 51 are provided with outturned flanges 58 to engage against the undersides of adjacent panels.

A plurality of extension connector or closure members 55 are provided for respectively closing the inner open ends of the laterally extending panel connectors l6. These individual closure members 55 are carried by the ridge cap I5, extending laterally from opposite sides thereof, respectively, to receive or fit over inner end portions of the panel connector members It to insure weathertight connections therewith. Preferably, the closure members 6!], in conformity to the general rectangular cross-sectional shape of the connector members It are hollow, each having a top wall 6! and opposite side walls 62. At the inner ends of the closure members 60, the side and end walls thereof may be provided with outturned flanges 63 which may be welded or be otherwise suitably secured flat to the connector member side walls 42 and the sides 62 may be welded at their lower edges to the connector member flanges 45, 46.

.Each of the laterally extending connector members I6 is preferably hollow and includes an elongated casing or cover preferably formed of sheet steel having a top wall 65 and side walls -66, as shown more clearly in Figure 10. The side walls 65 of the connector member l6 position outwardly of or enclose the upstanding side edge panel flanges 32 and the panel facing strips 33 to co operate therewith to effect weathertight joints. Each of the connector members it may be provided, as in the present construction, with a filler 58 which may be insulation material, wood or any other inexpensive material which will give added strength and rigidity, to the connector. At their outer ends, each of the connector members It is provided with an extended portion 64 of its top walla? bent down and under the panel edges and then up and along the underside thereof as at 5%, Figure '7. This forms a hooked end on the connector members [6 to hook under the outer edges of the panels I4 and overlie and close the opening between the spaced side edges of the .panels which lie outwardly of the building side walls it. In spaced relation along the length of each connector member [6, there is a plurality -of depending connecting rods 69 having their upper ends secured to and between depending legs iii of a pair of angle members H which may be welded or be otherwise suitably secured to the underside of the connector member top wall 65.

.{Ihese rods 69 extend downwardly respectively on the building side walls W.

as shown. The abutment members or clamps 12 may each be formed of a strip of sheet steel bent transversely to provide, when in position, an in-- verted U-shaped member having a top or web portion 14 through which the rod 69 extends and. against the underside of which the nut is tightened. Downturned sides 15 of the abutment I2; serve to space and locate the panels l4 relatively to each other and outturned lower flanges l6 abut the under surfaces of the facing strip flanges. The abutment members 12 and wing nuts 13 may come assembled with the connector members l6, as the widths of the abutment members may be such as to permit them to be swung around on the rods 59 to positions where they will pass through the openings between spaced side edges of the panel or the clamp and nut may be assembled on the rod after the connector member is placed in its approximate position on the panels.

In erecting the roof, the ridge member [3 is first erected merely by lowering it until it seats on the brackets H with opposite end portions of the ridge member locating in the bracket retainers formed by the upstanding side walls l9 and end abutment wall 25. The ridge member I3 is held against side and end movement solely by these socket type retainers, thus eliminating time and expense of bolting or otherwise securing this ridge member to the building walls. The roof panels M may now be lifted into place and their individual hangers 35 hooked over the upper portions of the ridge member l3 which supports the panels adjacent their inner end edges, the panels being further supported adjacent their outer end edges These hangers 35, in addition to supporting the inner ends of the panels it on the ridge member is below the upper edge thereof, also locate the panels transversely of the roof and restrain movement of the panels in this direction. With the panels M in their approximate relative position in the roof assembly, the panel connector members l6 can now be added. These connector members l6 are each swung to a position with the inner end raised so that the outer end may be hooked under the overhanging outer edges of the panels l4 and the connector member is then lowered onto the roof panels overlying the space between the spaced side edges of a pair of adjacent panels. In this position, the connector member l6 fits over and encloses the upstanding panel guard flanges 32 and the facing strips 33 carried by the adjacent edges of the pair of panels and seats against the upper surfaces of the panels. The abutment members or clamps 72 which may be carried by the connector members l6 as a part of its assembly are swung around to engage opposed surfaces of adjacent panel facing strips 33, thus spacing the panels M the proper distances apart with the outturned flanges T5 engaging the underside of the panels. The wing nuts 73 are now tightened down, drawing the connector members l6 down tightly against the upper metallic surfaces of the panels Hi to form leakproof joints therewith. If, for any reason, moisture should find its way under the lower edges of the connector member sides 56, it will be seen that entrance of the moisture into the building will be prevented by the upstanding panel guard flanges 32. After the laterally extending panel connectors l6 have been secured in place, the ridge cap fl'l ieiidg i e '1 t eiler MPW -P Iii nsQ t i erief lei mbe 'i we S a dl n i s ei {9 ith .min r-ei f 'q lih l el el r heeeii e w thus serving as apanel connector member. {Ifhe fr ear 1 a fi s; Over n -en l se h i nuts :55 Kare tightened v down ,to draw the ridge ,p p down tightly against the roofpanels [4. will be seenthat the ridge cap ,i5,.the g panel connector members A5 and the panels IA In; th the upstanding flanges 13 and ;7552 "around the side and end edges thereof proride ,doubl e ,protection against a leaking roof, n ifJWat er" lshould get undertl epanel connectors t6; sockets 7. e dl' i l c i -W r he aiaeain ente ur a o th el th Wate wi rsiil rh t ven e rom e t r n t buildin s-Wi ner 19 -.il .ee ene o t upsta d n lrerie l ier niangesfii and 32.
